fo all 'whom #may concerwj l Be it known that we, THoMAs firmnsoN and VILLIAM lViLniNsoN, subjects of county of Alameda and State of California, have invented new and useful Improvements in Disk Wheels, of which the following Vis a specification'.V Y v y This invention relates to improvements in metal disk wheels for moto-r vvehicles and resides in the provision of a strong, durable, simply constructed and comparatively inexpensive wheel which is made up without the usual hub construction and arranged so that the hub of an ordinary wood spoke wheel may be used.

One of the objects of the invention is to provide in a disk wheel of the character described a simple and reliable means for adapting the wheel for the use of the hub of,

an ordinary wood spoke wheel.

Another object of the invention is to provide for the use of demountable rims to facilitate the mounting of tires on and removal thereof, from the wheel.

A further object resides in the provision of la two disk construction which is made practical, strong and durable, through the use of a spacing element around the hub opening, which element serves also as a means for adapting the wheel for ready attachment to the hubs of dierent kinds of wood spoke wheels.

It has been the general practice in constructing disk wheels to provide complete hubs as a. part thereof whereby on the removal of the ordinary wood spoke wheels, the disk wheels are mounted on the axle spindles as complete wheel units. The lpresent invention eliminates the provision of hubs as parts of disk wheels and provides for the convenient use of the hubs of. the wood spoke wheels. Thus, wheels of the present invention may be constructed at a lower cost than disk wheels lwhich include in their construction the usual hub parts.

lVith the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described. illustrated in the accompanying drawings, and set forth in the claims hereto appended, it ybeing understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted towithout departing from the spirit i' i or sacrificing any of the advantages of' the n invention.

The embodiment of the invention'shown in the accompanying drawings comprises a wheel body made up of two metal disks l and 2, which disks are circular and provid- `ed with central registering openings 3. A ,80

combined spacing and adapting member 1i,

of annular form, is mounted between the disks around the `margins of the openings 3, the portions of said disks opposed `to the spacer being' flat and parallel to oneV an- S5 other. V4The spacer is preferably formed of some light, strong` metal, for example aluminum, and is preferablyof skeleton construction, having lateral flanges 5 extending from its margins and providedwith webs G'join- 'J0 ing the flanges extending around said margine. A plurality of openings 7 are provided in the member i adjacent the periphery thereof, said openings being cut through the outer periphery7 to facilitate the casting 95 of the openings in said member 4. These openings are adapted to aline with bolt open-- ings 8 in the disks, which openings provide for attachment of the wheel to a wood spoke wheel hub, as will be later more fully def scribed. f

The outer disk l is provided between its outer periphery and the portion engagedk with the spacer, with an annular convexity, shown at 9. convexity l0 is also provided in the disk. The inner disk is of concavo-convex formation to a point adjacent its outer periphery, from which point on it is ,straight and engaged with the opposite straight portion of U0 A similar but smaller annular in the disks provide for strength oi' con-A struction and permit of the disposition ot the margins of the disk su-ch that the vtelly and rim may be disposed inV properly centered relation to the hub. The Virregular formation ot' the body portion lends ornamentation to the wheel as well as strength of construction.

To attach t-he wheel constructed in accord` ance with the invention to an automobile, the wood spokevwheel is removed :from the axle spindle and the hub ot said Wheel then removed. The hub is then attached to the wheel ot this invention thus making a complete wheel ready for mounting on the axle spindle.

As shown in Fig. a, the hub is inserted through the opening in the center ot the wheel having a bearing on the adapter et, and the rear flange 16 of the hub abuts the rear disk and adjusted to bring the opening 17 thereof in registration with the openings 8in the disks. The hub AplateV 1S is then mounted in place and the hub bolts 19 are inserted through the plate, the openings 7 in the Vmember 4, and through the rear tiange of the hubs. Nuts 2Q are turned on said hub bolts to hold the hubrand wheel assembled. The other hub parts are then operated as is customary to attach the Wheel to the `axle spindle. In this way we may provide disk wheels of an inexpensive, simple construction consisting of but `few parts, mainly due to the fact that complete hub construe-tions built as a part of the wheels are not required because of the adaptability of our wheels to use ot the hubs of the wood spoke wheels for which the Wheels ot our invention are substituted. l

The removal of the hub from the wood spoke Ywheel may be etectedlbv a simple operation requiring but little time to carry out, and likewise the adaptation ot this hub to a wheel ot our invention may be made easily and quickly.

The combined spacer andV adapter 4 not Ionly serves for the purpose described .but reinforces the construction and makes possible a strong two disk wheel body in which the disks may bel constructed of light niaterial and because lof their peculiar shape will provide adequate strength and resiliency. The two disks construction also permits ot` the use of demountable rims which is aV time saving and convenient feature in disk wheels.

As a means :tor holding the spacer eiin place, thedisks 1 and 2 are provided on their inner sides around the margins of the openings Swith inward proiections 2i. These projections may be provided in forming said openings yby striking the material ot the disks inwardly. Said projections extend into the opening 7 in the spacer d and Vact as keys 'to hold the spacer in place.l The spacer is also provided with a beveled` tace 22 on its inner sideand -the inner disk 2 around itscentral opening is bent inwardlyY ber interposed between the disks and sur-- rounding the hub openingasaid disks and annular member having registering openings for reception `ot hub bolts, said disks having projections around the margins of the openings therein adapted to engage in the openings of the annular member, said yannular member having the Vbeveled tace 22, one of the disks being bent inwardly at the margin of the hub opening to engage said vbeveled face, and a felly band secured tosaid disks.

2. A combined spacer and adapter for use in connection with disk wheels comprising an annular body member, lateral iianges extending froni the margins of the body, webs joining said lianges, said body having a plurality ot openings therein adjacent lthe periphery thereof, which openings are cut through the periphery and are adapted to receive bolts, there being a bevel. t ce on the body portion at the inner periphery thereof.
